Renewable Avoided Cost & Consumer Compensation

Renewable Avoided Cost

The “avoided cost” value of renewable power is lower than our retail rate. This is due to the natural intermittency of solar and wind and the mismatch between renewable peak power and our early morning winter peaks and late afternoon summer peaks.

Because renewable energy may not be available during peak periods, your cooperative has to provide for the generation capacity and energy for those peak periods from other sources. For example, when solar energy is available mid-day, the resulting savings or “avoided cost” of solar energy is the avoided fuel cost and the avoided variable operations and maintenance cost from other generation sources.

In summary, the value of electricity varies throughout the day. It is most valuable during peak periods, which is early morning during winter and late afternoon during both summer and winter. It is less valuable in the middle of the day and least valuable in the middle of the night, which explains the value associated with avoided cost.

On a clear day (green curve), solar power generation does not match well with the time when your electric cooperative needs electricity the most.

Consumer Compensation

After careful consideration, RushShelby Energy has established compensation levels for consumer-owned
renewable energy that ensures equity for all member-consumers. It is important that compensation be fair to
both those who choose to interconnect a distributed generation device and those who do not. The payment
structure is a modified net metering approach as seen below.

 

Energy produced and used by the consumer, shown in light blue in the chart below, would be an energy
offset at your retail rate. The area shaded in green is energy returned to the grid that would be compensated at
the avoided cost rate.
